Background: Students at pre clinical level Fatima Jinnah Dental College are taught root canal treatment on endodontic typodonts. Technical quality of the treatments performed by these students was assessed to determine success teaching methodology and reinforcement tooth morphology concepts. Methodology: In this cross-sectional study, obturation 20 anterior 30 posterior typodonts were evaluated...

There are numerous examples reported in the literature that cite and document many disabling complications to the alveolar bone, neurovascular anatomy and maxillary sinus following overextension of root canal filling materials. Neural complications as a consequences of endodontic obturation as well as other server outcomes to overfill are a serious problem. These injuries require a thoughful st...

Management of a tooth with open apex is a challenge to the dental practitioners. Evaluation of the periapical healing is required in such cases by radiographic techniques. The objective of this paper was to assess the healing of a periapical lesion in a non-vital tooth with open apex treated with mineral trioxide aggregate (MTA) obturation using cone beam computed tomography (CBCT). The endodon...

This study was undertaken on 14 teeth in order to evaluate a new technique for radiation dose reduction during endodontic therapy. After examination of the preoperative film, usually available in the patient file, an apex locator (Root ZX) was used to measure the working length. Complete chemomechanical debridement was then performed, and the master cone was evaluated by a digital imaging syste...

BACKGROUND Successful obturation in the primary teeth demands complete dryness of the root canal system. AIM The purpose of this study was to determine the effect of 95% ethanol as the final irrigant before root canal obturation in primary teeth. MATERIALS AND METHODS A total of 20 extracted primary mandibular canines were biomechanically prepared and pre-obturated volume of each tooth was ...

October 2003 ORAL HEALTH 75 T he ‘Apical Control Zone’ is a matrix-like region created in the apical third of the root canal space. The zone demonstrates an exaggerated taper from the clinician defined apical constriction whether this is spatially a linear or point determination. This enhanced taper in the apical control zone provides resistance form against the condensation pressures of obtura...

OBJECTIVES To determine the optimal timing for post space preparation of root canals sealed with epoxy resin-based AH Plus sealer in terms of its polymerization and influence on apical leakage. MATERIALS AND METHODS The epoxy polymerization of AH Plus (Dentsply DeTrey) as a function of time after mixing (8, 24, and 72 hours, and 1 week) was evaluated using Fourier transform infrared (FTIR) sp...

OBJECTIVE To analyse the influence of root canal instrumentation and obturation techniques on intra-operative pain experienced by patients during endodontic therapy. METHOD AND MATERIALS A descriptive cross-sectional study was carried out in Ponferrada and Sevilla, Spain, including 80 patients (46 men and 34 women), with ages ranged from 10 to 74 years, randomly recruited. Patient gender and ...

Introduction: Primary root canal treatment success depends on a number of variables, including debridement and disinfection of the root canal system to remove all bacteria and diseased pulpal and dentinal tissues. Complex root canal anatomy, such as concealed isthmuses, apical deltas and lateral canals, hinder this objective, making instrumentation of these regions nearly impossible. Recent adv...
